100
) + 2976 X (1 +
13
100
) + 800(1 +
13
100
) = 416 X
    Remove a bracket on the left of the equation:
     2976 × 1 + 2976 ×
13
100
 + 2976 X (1 +
13
100
) + 800(1 +
13
100
) = 416 X
    The equation is reduced to :
     2976 +
9672
25
 + 2976 X (1 +
13
100
) + 800(1 +
13
100

    The equation is reduced to :
     
84072
25
 + 2976 X (1 +
13
100
) + 800(1 +
13
100
) = 416 X
    Remove a bracket on the left of the equation:
     
84072
25
 + 2976 X × 1 + 2976 X ×
13
100
 + 800(1 +
13
100
) = 416 X
    The equation is reduced to :
     
84072
25
 + 2976 X +
9672
25
 X + 800(1 +
13
100
) = 416 X
    The equation is reduced to :
     
84072
25
 +
84072
25
 X + 800(1 +
13
100
) = 416 X
    Remove a bracket on the left of the equation:
     
84072
25
 +
84072
25
 X + 800 × 1 + 800 ×
13
100
 = 416 X
    The equation is reduced to :
     
84072
25
 +
84072
25
 X + 800 + 104 = 416 X
    The equation is reduced to :
     
106672
25
 +
84072
25
 X = 416 X

    Transposition :
     
84072
25
 X − 416 X = -
106672
25

    Combine the items on the left of the equation:
     
73672
25
 X = -
106672
25

    The coefficient of the unknown number is reduced to 1 :
      X = -
106672
25
 ÷
73672
25
        = -
106672
25

9209

    We obtained :
      X = -
13334
9209
    This is the solution of the equation.

    Convert the result to decimal form :
      X = - 1.447931
